HOISTING-BUCKET.

SPECIFICATION forming part of Letters Patent No. 424,571, dated April 1,1890.

Application filed January 2, 1890. Serial No. 335,705. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES PAY, of Providence, in the State of RhodeIsland, have invented certain new and usefulImprovements inHoisting-Buckets; and I do hereby declare that the followingspecification, taken in connection with the drawings making a part ofthe same, is a full, clear, and exact description thereof.

Figure 1 is an end View of the bucket closed. Fig. 2 is a top view ofthe same. Fig. 3 is a vertical section showing side view of workingmechanism. Fig. a is an end view of bucket open. Fig. 5 shows the mannerin which the levers are attached to and operate upon the shaft. Fig. 5is a horizontal section of same,

The object of my invention is to produce a bucket in which the twohalves shall be capable of a wider or greater opening than those now inuse and at the same time be possessed of greater closing-power, both ofwhich features are especially useful in operating .upon coarse material;and it consists in the combination and arrangement of devices ashereinafter described.

In a bucket of this class it is desirable be fore dropping it upon thematerial to open the two halves as wide as possible, and at least to anextent whereby the operating or cutting edges will be brought into aline perpendicular to the surface of the material to be removed Thisopening serves to give the bucket a greater downward tendency in closingand enables it to grasp or secure agreater quantity of material.

In the drawings, A A are the two halves of the bucket, which togetheroccupy about half a circle and are provided with elbow-levers B B, thevertical arms of which are riveted to and strengthen the edges of thehalves A A, while the remaining arms eXten d horizontally toward thesides of the bucket.

C C are the two parts of a bale or crossrod connected by a block D,through which is a passage for the operating-cable. The rod C O hasvertical ends E, which serve as bearings for the shaft F, and to whichare attached the cross-bars or levers G G. To the ends of the rod C Oare riveted straps or cars II II, the vertical ends of which are withoutthe bucket, and to which are pivoted the elbow-levers B B, to which thehalves of the bucket are attached.

The horizontal ends of the levers B B and the ends of the levers G G areprovided with sheaves J J K K, and upon the shaft F is a drum M.

N N are side chains, which connect the bucket with a bar 0, the wholebeing supported and raised or lowered by a cable P.

Q is the operating-cable, which rotates the shaft F in closing thebucket through its action upon the drum M. The ends of the cross-bars orlevers G G are somewhat de' pressed to secure the requisite leverage inclosing the bucket.

R R and S S are chains having their ends secured to the levers G G, andpass around the sheaves J J and K K, and under, over, and around theshaft F, respectively.

Commencing with the bucket closed, as shown in Fig. 1, as it is let downby the cable P the cable Q is slackened, when the halves A A, beingsupported from their outer edges by the chains N N, will open by theirown weight, the width of the opening depending upon the amount of slackin the cable Q, and being at all times under the control of theoperator. The halves A A having been opened, as shown in Fig. 4, orwider, if desired, the bucket falls upon the material to be removed. Theoperating-cable Q is then drawn upward, which, as it unwinds from thedrum M, rotates the shaft F and winds up the chains R R and S 5. As thechains R R and S S become wound upon the shaft F they will draw togetherthe ends of the levers G G and B B until the two halves of the bucket AA are brought together. As the halves A A are thus being closed theyhave a tendency to dig down into the material, which results in fillingthe bucket. As soon as the bucket is closed it is hoisted up anddischarged at the proper time and place by the slackening of the cableQ, as it is well understood.

It will be observed that the vertical space required for the operationof the bucket is less than that necessary for the practical andsuccessful operation of other buckets now in use, and that at the sametime the two halves or parts A A may be opened to a width which willbring their edges in a vertical line With the material to be removed.The Width of the opening tends to insure the downward or diggingtendency While the bucket is being closed and the securing of a fullload even when the material to be removed is very coarse.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the elbow-levers B B, the angled levers G G, allprovided with sheaves, the chains R R and S S, and the rotating shaft F,the whole arranged and opcrating together to close the parts of thebucket, as described.

2. The combination of the two chainsR R and S S with the shaft F, two ofsaid chains being Wound upon each end of said shaft, the drum M, and thecable Q, the Whole constructed and operating upon the levers B B and G Gto close the bucket, as described.
